According to the photographing optical lens assembly of the presentdisclosure, there is an air space between every two lens elements of thefirst lens element, the second lens element, the third lens element, thefourth lens element and the fifth lens element that are adjacent to eachother. That is, each of the first through fifth lens elements is asingle and non-cemented lens element, and there is a space between everytwo adjacent lens elements. Moreover, the manufacturing process of thecemented lenses is more complex than the non-cemented lenses. Inparticular, a cementing surface of one lens element and a cementingsurface of the following lens element need to have accurate curvature toensure these two lens elements wilt be highly cemented. However, duringthe cementing process, those two lens elements might not be highlycemented due to displacements and it is thereby not favorable for imagequality of the photographing optical lens assembly. Therefore, accordingto the photographing optical lens assembly of the present disclosure,having an air space in a paraxial region between every two adjacent lenselements avoids the problem generated by the cemented lens elements.

The first lens element has positive refractive power, so that the mainlight converging ability can be provided so as to control the totaltrack length of the photographing optical lens assembly and reduce thevolume thereof.

Therefore, the telephoto effectof the photographing optical lens assembly can be performed bycorrecting off-axial aberrations thereof.

The photographing optical lens assembly can further include at least oneprism on the optical axis. When an axial distance between an object-sidesurface of the first lens element and the image-side surface of thefifth lens io element is TD, and a sum of light path lengths on theoptical axis in the at least one prism is TP, the following condition issatisfied: 0.20<TD/TP<2.0.

According to the photographing optical lens assembly of the presentdisclosure, the lens elements thereof can be made of glass or plasticmaterials. When the lens elements are made of glass materials, thedistribution of the refractive power of the photographing optical lensassembly may be more flexible to design. When the lens elements are madeof plastic materials, manufacturing costs can be effectively reduced.Furthermore, surfaces of each lens element can be arranged to beaspheric, since the aspheric surface of the lens element is easy to forma shape other than a spherical surface so as to have more controllablevariables for eliminating aberrations thereof, and to further decreasethe required amount of lens elements in the photographing optical lensassembly. Therefore, the total track length of the photographing opticallens assembly can also be reduced.

According to the photographing optical lens assembly of the presentdisclosure, each of an object-side surface and an image-side surface hasa paraxial region and an off-axial region. The paraxial region refers tothe region of the surface where light rays travel close to an opticalaxis, and the off-axial region refers to the region of the surface awayfrom the paraxial region. Particularly, when the lens element has aconvex surface, it indicates that the surface can be convex in theparaxial region thereof; when the lens element has a concave surface, itindicates that the surface can be concave in the paraxial regionthereof. According to the photographing optical lens assembly of thepresent disclosure, the refractive power or the focal length of a lenselement being positive or negative may refer to the refractive power orthe focal length in a paraxial region of the lens element.

According to the photographing optical lens assembly of the presentdisclosure, the photographing optical lens assembly can Include at leastone stop, such as an aperture stop, a glare stop or a field stop. Saidglare stop or said field stop is for eliminating the stray light andthereby improving the image resolution thereof.

According to the photographing optical lens assembly of the presentdisclosure, the image surface of the photographing optical lensassembly, based on the corresponding image sensor, can be flat orcurved. In particular, the image surface can be a curved surface beingconcave facing towards the object side.

According to the photographing optical lens assembly of the presentdisclosure, an aperture stop can be configured as a front stop or amiddle stop. A front stop disposed between an object and the first lenselement can provide a longer distance between an exit pupil of thephotographing optical lens assembly and the image surface, and therebyobtains a telecentric effect and improves the image-sensing efficiencyof the image sensor, such as CCD or CMOS. A middle stop disposed betweenthe first lens element and the image surface is favorable for enlargingthe field of view of the photographing optical lens assembly and therebyprovides a wider field of view for the same.

According to the photographing optical lens assembly of the presentdisclosure, the photographing optical lens assembly can be applied to 3D(three-dimensional) image capturing applications, in products such asdigital cameras, mobile devices, digital tablets, smart TVs,surveillance systems, motion sensing input devices, driving recordingsystems, rearview camera systems, aerial photography and wearabledevices.

In the image capturing apparatus,the photographing optical lens assembly is movable for stabilizing animage, for example, the image capturing apparatus can further include anoptical image stabilizer (OIS). Therefore, image quality of thephotographing optical lens assembly can be further enhanced. Preferably,the image capturing apparatus can further include a barrel member, aholder member or a combination thereof.

According to the present disclosure, an electronic device is provided,which includes the aforementioned image capturing apparatus. Therefore,image quality of the electronic device can be improved.
